of the control members thereb facilitated. Means-are provided whereby the reproducer'is caused to be raised from the record immediately'at the end of the story thereon andcaused to be moved toward the beginning of its path of movement. Said means include the arm 32 pivotally supported by the record holder 12 and extended above the record turn table carried thereby. Each tablehas such an arm associated therewith. Said arm is provided with a part extendedover the record which has an opening therein in which the step member 34 in adjustably secured. Said step member has an end portion in the form of a pointer which is adapted-to be set above the end of the story on the record. During the movement of the reproducer in engagement with the record the arm 29 carried by the reproducer control arm is moved in proximity to said member 34 and, near the end of its movement, engages and moves it backward causms the lever 35, having arms 36 and 37, to be moved. For the control o mechanism by driving screw and engaging the return screw. While the reproducer is being returned by the return screw, a new record is placed in playing position by, the record holder 12 bein turned on the shaft 10. Said record holder 12 has the pins 38 adapted to he engaged by the arm 39 for the movement of said record holder.

Means are provided whereby the reproducer stylus may be moved to the beginning of the new record, or it may be moved beyond the beginning of the story thereon and then moved back on the playing stroke without, however, engaging the record. Said means include the arms 40, one for each record, which are pivotally supported at 41 to a disc 42 secured to a hub bv which it is fixed to the Shaft 10 of the machine. Said arm. 40s extended upwardly above the record turn table and has a squared passage therethrough at its upper end, in which the stop member 43 is adj ustably secured and fixedin adjusted position by a clamping screw. Said stop member terminates in an upturned portion which is adapted to be engaged by an arm 29 extended from the reproducer control arm during the latter part of its return movement, and it and the pivoted arm 40 are moved backward thereby to adjust the mechanism for the return or playing movement of the machine. Said stop member 43 is so positioned that it is engaged by the arm 29. to cause the return of the reproducer at the desired point. which may vary with different records.

The shifting of the reproduoer carriage from the return to the feed screw is performed by mechanism set in operation by the lever 44 pivotally supported at 45 to a supporting standard of the machine. Said lever is formed with a vertical extension 46 having a terminal portion in proximity to said arm 40 hearing the stop member 43. Upon the backward movement of said arm 40 because of its engagement with the reproducer control arm, or equivalent, the lever 44 is moved to operate mechanism to cause the shifting of the reproducer carriage from the return to the feed screw.

When the reproduced is being returned the arm 29 which engages the stop member 43 is in a raised position. After it has en gaged such stop member to cause the shitting of the reproducer carriage from the return to the feed screw. the arm 29 and the reproducer arm 23 and its control arm. fall slightly and said arm 29 is then retained by the member 47, adjustably fastened in the arm 42 by thumb screw.

The reproducer is now being moved in a playing direction. without however. be ing in engagement with the record. and the arm 29 slides over said member 47.

lVhen the reproducer has been moved a suitable distance on its playing stroke, the

arm 29 reaches the end of said member 47 and drops off, and the stylus of the reproducer may engage the record at the beginning of the story thereon, the beginning of the record having been previously located and the record having been clamped to its turn table, which is locked in a predetermined position.

The reproducer stylus may be arranged to engage a stationary record at a prearranged point in one of the cut lines on the record, the record then started turning. and by the time the stylus reaches the. point at which the selection on record begins the record will be turning at the proper playing speed. thus eliminating false tones at start of record.

The movement of the reproducer of the talking machine is multiplied in the controller arm for the stereopticon. The multiplying means here shown comprise the rack (Figs. 1 and 4) slidable in the bearing 71 carried by the frame of the talking ma chine and engaged by the arm 72 fixed to the reproducer carriage by which said rack is driven from said carriage.

A second rack 73 having magnified re producer carriage motion and bearing the controller arm slidably arranged in the bearing 74-. lllultiplying means comprising the gears 75, 76 and 77 serve to multiply the motion of the rack 70 to said rack 73.

A controller arm 78 is fixed to said rack 73 and extends over the controller and bears at its extremity several spaced-apart depending lingers 79, 79", 79 and 79 (Fig. 4) which bear contact members.

The stereopticon controller comprises the hexagonal drum 80 having as many sides as there are records of the talking machine, fixed to the extended portion of the talking machine shaft 10 and rotatable therewith. The controller drum is so fixed to said shaft that the flat side is on top, or under the controller arm, when corresponding record is in playing position. Each flat side bears the controller unit support 81 having tapered side walls in which the controller units are slidably received and clamped by the screws 82. a

The controller unit comprises a block 83 of insulating material having tapered side walls and bearing on its top surface a plurality of conducting bars 84, 84", 84 and 84 (Figs. 4 and 1) which may extend the length of the block. The bar 84 is adapted to be entirely without lateral projections while said other bars may have projecting members as 85. Said projections may be either integral with said bars or separate therefrom and adjustably secured thereto as at 85, in which case. said bars 84*, 84 and 84 are slotted to admit the passage therethrough of clamping bolts 86. and the block 83 is formed with slots 87 to receive said bolts.

Said finger 79 of the controller arm 78 is provided with a brush contact member 19, which is adapted to be in continual contact with said bar during the movement ofsaid controller arm. Said other fingers 79, 79 and 79 are provided with a spring pressed trip contact member comprising'the bar 91 pivotally connected thereto which is adapted to engage the projections 85 of said bars 84", S4 and S4 for accurate electrical contact therewith and ride over same during a certain ezgztent of movement of said controller arm and thereafter snap away therefrom. All of said contact members 91 carried by said fingers 79", 79 and 79 are in permanent electrical connection with brush 89 through the metallic end portion of said arm, said end portion being insulated from the frame of the machine by the insulating bushing; 93 interposed intermediate said arm 78.

The projecti0ns85 are adapted to be located on said bars 8 1 184 and 84? at points corresponding to points on the record at which it is desired to present a new illustration and the stereopticon control circuit is adapted to be made insuccession through said bars 84", 84 and 84-, and then again in the same order for a purpose to be hereinafter described.

As there are four'controller bars to each controller unit and said bars have extended portions extending onto under side of said controller units, four collector rings 95", 95 95 and 95 are arranged on the outer end of the controller concentric with said shaft 10 and separate leads evtend therefrom to spring plates 96, 96". '96 'and 96 in each support 81which are in detachable connection with said bars, whereby corresponding, bars in all units are connected to the same colle'ctor'ring.

A standard 97 supported by the frame of the machine bears four independent brushes 98, 98', 98 .and 98 which engage said collector rings'and stereopticon controller leads are connected thereto. 7

Each unit support may be provided with an indicator as 99 and each unit may also be )rovided with a scale by which the unit may e adjusted with respect to the support and the projections 85 adjusted on the bars. The controller arm 78 is also provided with a pointer 100 movable over said scale where-- by adjustments of the controller may be facilitated.

It is necessary that the controller arm 78 be raised from engagement with the controller at the end of its movement and before the talking machine: is moved to present a new record for playing, and a new controller unit for same, to permit such movement. Means for'aceomplishin; this result comprises the lever 102 fixed to the controller arm of the talking machine and extends under the'arm 78. Said talking machine control arm, in its movement to elevated position, serves to also raise the electric controller arm 78 to Jer- Init the turning of the controller. r aid controller arm 78 for this purpose is pivotally supported at 103 to the rack 73. A rest for the arm 102 when in lowered position is shown at 102 The picture machine comprises the two independent and similar slide holders 105 and 106 rotatably supported on the shatt'or post 107 which is fixed at its ends to the frame 108 of the machine;

Each slide holder comprises the disc 105 (Figs. 2 and 3) upon which a plurality of spring, plates 1 10, arranged in pairs, are supported. Slides are adapted to be movably held between each pair of plates. The periphery of the disc is provided with a plurality of pins 111 by which the slide holder is moved for the presentation of a new slide, and may also bear a series of numbers to denote the number of the slides in the total series of slides. The slides in the two holders are -alternately numbered; that is, the slidesbearing the even numbers are in one holder, and those bearing the odd numbers are in the other holder, and the slides in the two holders are alternately presented. An arm 112 fixed to the supporting post 107 beneath the slide holder bears the pointer 113 to indicate the slide that. is presented and a spring'finger 114 carried by said arm is adapted to yieldingly engage the pins 111 to hold the slide holder in adjusted position.

l'he light house 115 (Fig. 5) and lenses 1 H3 and 116 are of usual construction. Two such houses and sets of lenses are provided, one for each slide holder, and are supported. one above the other, on the standard 117.

The slides contained in the slide holder are adapted to be moved from the holder to a position between the lenses 116 and 116* where they are support-ed by the table 125. For this purpose a frame 126 is provided. Said frame is carried by the rod 127 which is slirlahly supported by the bearing 128 secured to said post 107 above the slide holder. Said frame 126 is arranged so the plates in the slide holder may pass between its arms. For the presentation of a slide, the frame is moved outwardly and the inner arm 126 (Fig. 2) thereof engages the edge of 'a slide and moves it from the slide holder onto the table 125. In the withdrawing of the presented slide the outer arm of the frame engages the slide and returns it to its holder.

The rod 127 (Fig. is reciprocated in its bearing 128 by the arm 130 which is fixed to a sleeve 131 supported on a supporting post 132 fixed to the frame of the stereopticon and retained in position thereon by the collars 133. A link 134 serves to pivotally connect the end of said arm 130 with the end of said rod 127 for its reciprocation.

The picture machine is driven from the main driving shaft chine mounted on the shaft wheel 136 by the link in Figs. 1. and 5 supports one end of the to the upright 20 of the talking maas follows -A sprocket wheel 135 20 drives the sprocket chain 137' (as .shown A supporting post 20 shatt26, Said is secured to the shaft the posts 139.

The picture machine operates in the,,following manner :The idler gear 168' Fig. 5) engages the driving gear'143, thereby turning the main operating shaft 122 of the picture machine one-half a revolution, said. shaft being positioned by the notches 165. The sleeve 131 (Fig, 3) is provided with a cam member fixed thereto, aving theprojectingarms 174 and175 (Figl'f Apin 17 6 and a toothf177 are arranged on the disc member l66 which is secured to' the main operatingshaft 122.; Said pin 176 is adapted to engage the cam arm 174, thereby: causinga"picture slidein position for pres; ehtation on' the support 125' to be returned onto the slide holder105, by the arms'.126%., (between which the ,slide positioned). and cooperating members 127, 134,180.,and'131, At this instant the tooth177-engages one of] the pins 111, thereby t'urn ing the slide holder to so position same that, uponthe. pin 176' engagingthelcam, arm '175, amew slide will be moved (out; of thesl'ide holder 105 into position j for, presentation, .on a the, support 125 by thearms 126 and e'rating members 127, 134, 130a nt1131; 'pin and finger mounted on'the d .is'c 16 oper ates the upper slide holder in the same man- 1.00 ner as the pin 17 Gandfin er 177 on the disc 166 operates the lower sli e holder. During: one half a revolution of the "shaft 122 the lower slide holder is operated and, on the other half revolution, the upper slide holder 10:; is operatedto move a new-picture slide into position for. presentation. 7

A circuit breaking means, or commutator, (Figs. 7, 8 and 9) in the electric control circomprises three conducting segments 178 (Fig. 9) spaced apart and electrically connected, also three other conducting segments 179, 180 and 181, the said conducting segments being mounted on a disc 182 of insulating. material. Said segments are adapted to e engaged by a brush having the arms 183, 184 and 185. armed wheel member 186, and adapted to be turned on the shaft132, between the stops 187, by the four-armed wheel-shaped member 188 secured to the main operating shaft 122 of picture machine, said wheel member 188 having four arms 188 which are adapted to engage the arms 186 of the member 186. During one operation of the picture machine to present a new picture the shaft 122 turns one-half a revolution, together with the wheel member 188 '(Figs. 7' and 8), thereby be turned one 122 beneath said brush'and'is sup the post 132. An inner c'llector ring"l99 is carried by said plate, which the brush 197 is in continual engagement. An intermediate segment 200, associated with the circuit of the lamp 202 for the lower unit of the picture machine, is carried on the face of said plate and terminates at each end in bared resistance coils 200, the convolutions of which are adapted to be engaged by the brush 197 during the movement of said arm 197, in the direction of the arrow, to first gradually increase the illumination of the lower lamp by cutting out resistance in the lower lamp circuit and crease the illumination thereof by cutting in resistance and, finally, by breaking the circuit. An outer segment 201 for the upper lamp is similarly arranged on said plate 198 and terminates in the resistance coils 201 at each end, and said brush 197 is adapted to engage said segment and coils. It will be noted that the resistance coils of the outer and intermediate segments are opposite each other, whereby the illumination of one lamp is "gradually decreased while that of the other is radually increased, to provide for the disso ving of one picture into another. The circuit of one lamp is preferably broken during the period of maximum illumination of the other lamp.

A modified form of drive for the picture machine is shown in Fig. 10, the sprocket wheels 136 and link chain 137 (Fig. being replaced by a belt pulley a adapted to be secured to the shaft 138 and driven by the pulley belt 205 from a separate motor, preferably an electric motor. This modified form permits the picture machine to be located in another part of the room from that of the talking machine. operating as previously described, and securing the reliability of operation obtainable with continuously running electric motors.

The electric service; for the said talking and picture exhibiting machine may be supplied through a common Time clock operated switch, whereby the said machine may be started and stopped automatically by said switch.

It may be seen that with the construction above set forth the necessary continued accuracy of presentation of the selections of the records and the slides in obtained.

It will be understood that while the illustrated machine shows a means whereby the matter on the talking machine records, and the pictures relating to same are autoanath cally returned to synchronism after a de parture from synchronous operation. that many other means may be arranged to ac then to gradually decomplish the general result, such a: automatically 'causingthc various parts of apparatus to, be arranged incorrect relation to eaclr' other,"at prearranged points in its cycle o'f' operati'oii'or at the end of each cycle of pperation; such: wiriations and modificationsfinthe means 'bypwhich' the object is attained are within'the-scope'df' my invert tion.

It will also be understood'that while I have here shown the pictures in the form oi glass lantern slides, the pictures may be arranged in other forms, such as pictures being part of a long single strip of flexible film, or short sections detachably joined, or individual pictures being part of individual films detachably supported on a carrier, and suitable means for displaying same in timed relation-to matter on talking machine records, as herein described, without de arting from the spirit of my invention.

ile I have descirbed a practical embodiment of my invention, the same is not limited to the details described, or the form, relation, or construction of parts, but that many and wide modifications may be made therein without departing from the spirit of mg invention.
